Depending on how fast you are trying to go, I have seen one that was made from an old lawn mower motor and a BMX, had a fair size gear on the back wheel too from memory. It went ok, but certainly not overly fast. I would think the whipper snipper motor would need some serious gear reduction.

A guy who lived near us use to have a whipper snipper motor on his bike and he would ride along the highway every day.
It seemed to get up to some pretty impressive speeds to
I'm interested in it so when you get going post some pics

CHEERS TIM.

Why not take the fuel tank off while welding? They are usually easy to get off.

Gday all

When I was 15 I made a Victa Powered BMX Pushbike. I picked up a few Victa lamnmowers from the local tip and a BMX pushbike. I horizontally mounted the engine into the frame and used a skateboard wheel to run on the crankshaft. Victas have a tappered crankshaft and had a boss that pushed onto the taper.

I had a Suzuki RM 250 Carb on the motor and man it used to go. I was clocked by the copper in the town I lived in riding at 90km/h up a hill out of the town. I have photos of it somewhere.

The fun ended when I crash landed and broke my wrist requiring SS screws to be inserted in my wrist.

My little bro made a powered bmx by mounting the engine over the front wheel and used a skateboard wheel with grooves cut into it using and angle grinder to drive the front tyre, the bloody thing could keep up with traffic. There were 2 long brackets that attached to the wheel studs and another of the top of the forks somewhere. I have one of those scooter engines with centrifugal clutch here that i'm still deciding what to do with.
